C-Clear™

Total Carbon Emissions (TVOC) is an important indicator for the evaluation of materials and automotive parts of VOC. The indicator is tested by machines, so avoid the subjectivity in the test. The requirements of the OEMs is usually less than 50 μg/g, and the requirements of the limousine is below 30 μg/g. Products of KUMHO-SUNNY not only meet the requirements of the OEMs, but also reaches industry's top level in the control of TVOC.

With the popularizing of cars, in-car air pollution(the silent killer to health), is getting more attention from car owners, which is also listed in the top ten threat to human health by W.H.O.

The in-car air pollution (e.g. benzene, toluene, styrene) is mainly from VOC emitting from vehicle interior parts such as plastics, leather, textile and cemedin, which will cause toxic symptoms like fatigue, headache and nausea, when it reaches to a certain concentration, and damage liver, kidney, brain and nervous system in serious cases, resulting in memory loss and affecting reproductive function, even leukemia or cancer.

C-Clear is an ultra-low emission plastics to prevent in-car pollution. According to the third-party test results, the emission of C-Clear with the least chemical emission has dropped by 60% more than the traditional ones, which is far lower than the VOC emission standard of all major automotive companies. It controls in-car air pollution at the source, providing customers a healthy and safe driving environment. (C-Clear PC/ABS TVOC﹤10μgC/g, C-Clear ABS TVOC﹤18μgC/g)

1）Molecule Design

The amount of residual monomer and the generation of low molecular oligomers are controled effictively at the very beginning of polymerization process by using a special compatibility agent, which can effectively prevent degradation of ploymers and repair small molecular chain to extend them to long ones.
